Laparoscopic hepatectomy is a safe surgical approach for treating both benign and malignant hepatic lesions. This small series showed no mortality, low morbidity and good cosmetic results.

Background:Laparoscopic hepatectomy has presented great importance for treating malignant hepatic lesions. Aim:To evaluate its impact in relation to overall survival or disease free of the patients operated due different hepatic malignant tumors. Methods:Thirty-four laparoscopic hepatectomies were performed in 31 patients with malignant neoplasm. Patients were distributed as: Group 1 - colorectal metastases (n=14); Group 2 - hepatocellular carcinoma (n=8); and Group 3 - non-colorectal metastases and intrahepatic cholangiocarcinoma (n=9). The conversion rate, morbidity, mortality and tumor recurrence were also evaluated. Results:Conversion to open surgery was 6%; morbidity 22%; postoperative mortality 3%. There was tumor recurrence in 11 cases. Medians of overall survival and disease free survival were respectively 60 and 46 m; however, there was no difference among studied groups (p>0,05). Conclusion:Long-term outcomes of laparoscopic hepatectomy for treating hepatic malignant tumors are satisfactory. There is no statistical difference in relation of both overall and disease free survival among different groups of hepatic neoplasms.

HEADINGS -Laparoscopy. Hepatectomy. Liver neoplasms/surgery. Neoplasic metastases.ABSTRACT -Background -Resection of neoplasms arising in the posterior right sector is usually a technical challenge due to approach difficulties. Additionally, laparoscopic hepatectomy has become an interesting alternative with several advantages (low morbidity, short hospital stay, early return work activities and good cosmetic results). Aim -To report a series of patients who underwent laparoscopic right posterior sectioniectomy performed by a single surgical team. Methods -Five patients were operated. Their ages ranged from 21 to 63 years (median 43 years). There were four women and one man. Etiology of the neoplasm was: adenoma (n=2), hepatocellular carcinoma (n=1) and metastasis (n=2). There was a single lesion in three cases (60 %). The mean lesion diameter was 3,3 cm (1,8-5). It was analyzed: operative time, intraoperative bleeding, morbidity, length of stay and time of return to usual activity. Results -The mean surgical time was 160 minutes (90-260). The mean intraoperative blood loss was 200 ml (0-500). None of the patients received transfusions. There was no mortality and no morbidity. The median hospital stay was three days (2-5). The median length of time taken to return to day-to-day activities was 12 days (7-20). The median follow-up period was 13 months (1-20). There was no tumor recurrence. Conclusion -Laparoscopic right posterior sectioniectomy (bi-segmentectomy VI + VII) is a good option to treat hepatic tumors located in the posterior sector of the right lobe. It is a safe procedure that avoids large incisions with no mortality or morbidity is this series. This approach also bring good cosmetic result and early return to work.RESUMO -Introdução -A ressecção de neoplasias no setor posterior direito costuma ser um desafio técnico pela dificuldade de sua abordagem. Adicionalmente, as hepatectomias laparoscópicas tem se tornado alternativa interessante em virtude de muitas vantagens (baixa morbidade, curto tempo de internação, retorno precoce as atividades laborais e bons resultados cosméticos). Objetivo -Relatar experiência em doentes submetidos à setorectomia posterior direita laparoscópica por uma única equipe. Métodos -Cinco doentes foram operados entre novembro de 2008 a agosto de 2010. A idade variou de 21 a 63 anos com mediana de 43 anos. Foram quatro mulheres e um homem. A causa das neoplasias foi: adenoma (n=2), hepatocarcinoma (n=1) e metástases (n=2). A lesão foi solitária em três casos (60 %). A média do tamanho das lesões foi 3,3 cm (1,8-5). Foram analisados: tempo cirúrgico, sangramento operatório, morbimortalidade, tempo de internação e tempo de retorno à atividade habitual. Resultados -A média de tempo cirúrgico foi de 160 minutos (90-260). A de sangramento intra-operatório foi de 200 ml (0-500). Nenhum doente foi transfundido. Não houve mortalidade e a morbidade foi nula. A mediana de internação foi de três dias (2-5). A mediana de retorno às atividades cotidianas foi de 12 dias (7-20). A mediana de...

Background:Laparoscopic distal pancreatectomy has been the choice for resection of distal pancreas lesions due many advantages over open approach. Spleen preservation technique seems minimizes infectious complications in long-term outcome. Aim:To present the results of laparoscopic distal pancreatectomies with spleen preservation by Kimura´s technique (preservation of spleen blood vessels) performed by single surgical team. Methods:Retrospective case series aiming to evaluate both short and long-term outcomes of laparoscopic distal pancreatectomies with spleen preservation. Results: A total of 54 laparoscopic distal pancreatectomies were performed, in which 26 were laparoscopic distal pancreatectomies with spleen preservation by Kimura´s technique. Mean age was 47.9 years-old (21-75) where 61.5% were female. Mean BMI was 28.5 kg/m² (18-38.8). Mean diameter of lesion was 4.3 cm (1.8-7.5). Mean operative time was 144.1 min (90-200). Intraoperative bleeding was 119.2 ml (50-600). Conversion to laparotomy 3% (n=1). Postoperative morbidity was 11.5%. Postoperative mortality was null. Mean of hospital stay was 4.8 days (2-14). Mean time of follow-up period was 19.7 months (2-60). There was no neoplasm recurrence or mortality on evaluated period. There was no infectious complication. Conclusion:Laparoscopic distal pancreatectomy with spleen and splenic vessels preservation is feasible, safe, and effective procedure. This technique presented both low morbidity and null mortality on this sample. There were neither infectious complications nor neoplasm recurrence on long-term follow-up period.

Background: Percutaneous drainage for pyogenic liver abscess has been considered the gold-standard approach for the treatment on almost of the cases. However, when percutaneous drainage fails or even in some especial situations, as multiloculate abscess, lobe or segment surgical resection can solve infectious clinical condition. Aim: To report a series of patients who underwent hepatectomy for pyogenic liver abscess performed by a single surgical team. Methods: Eleven patients were operated with ages ranging from 45-73 years (mean and median 66 years). There were eight men and three women. The etiologies were: idiopathic (n=4), biliary (n=2), radiofrequency (n=2), direct extension (n=1), portal (n=1), and arterial (n=1). The mean lesion diameter was 9.27 cm (6-20 cm). Results: The mean operation length was 180 min (120-300). The mean intra-operative blood loss was 448 ml (50-1500). Surgical approaches were: right hepatectomy (n=4), left hepatectomy (n=3), left lateral sectioniectomy (n=1), right posterior sectioniectomy (n=2), resection of S8 (n=1), and S1 (n=1). Postoperative morbidity rate was 30%, while mortality was null. Median hospital stay was 18 days (5-45). The median follow-up period was 49 months (13-78). There was single lesion recurrence. Conclusion: Hepatectomy can be done as exception approach for pyogenic hepatic abscess treatment; it is a good therapeutic option in special situations.

Background: Laparoscopic distal pancreatectomy (LDP) is the preferred approach for resection of tumors in the distal pancreas because of its many advantages over the open approach. Aim: To analyse and compare short and long-term outcomes from LDP performed through two different techniques: with splenectomy vs. spleen preservation and splenic vessel preservation. Method: Fifty-eight patients were operated and subsequently divided between two groups: Group 1, LDP with splenectomy (LDPS); and Group 2, LDP with spleen preservation and preservation of splenic vessels (LDPSPPSV). Results:The epidemiological characteristics were statistically similar between the two groups (age, gender, BMI and lesion size). Both the mean of operative time (p=0.04) and the mean of intra-operative blood loss (p=0,03) were higher in Group 1. The mean of resected lymph nodes was also higher in Group 1 (p<0.000). There were no statistic differences between the groups in relation to open conversion, morbidity or early postoperative mortality. The mean hospital stay was similar between groups. Pancreatic fistula (grade B and C) was similar between the groups. The mean of overall follow-up was 37.6 months (5-96). Late complications were similar between the groups. Conclusion: Both techniques were superimposable; however, LDPS presented, respectively, higher intra-operative bleeding, longer duration of the operation and higher number of lymph nodes resected. No differences were observed in the studied period in relation to the appearance of infections or neoplasm related to splenectomy during follow-up. Maintenance of the spleen avoided periodic immunizations in patients in LDPSPSV. It is indicated in small pancreatic lesions with indolent course.

Hepatectomy has been the standard treatment for metachronic metastases of non-colorectal (NCR) origin, mainly when the disease-free interval is more than two years. Laparoscopic hepatectomy has become the golden standard mainly for left side resections, due to lower morbidity, shorter hospital stay, early recovery and good cosmetic outcome. The authors report the case of a female patient with two metachronic metastases (ten years of disease-free survival), of non-colorectal origin (adenocarcinoma of small intestine), treated by laparoscopic left lateral segmentectomy (left hepatic lobectomy) with success. The postoperative progress was satisfactory. To date, the patient has presented no tumoral recurrence (six months of follow-up period). Laparoscopic left lateral segmentectomy can be satisfactorily performed in selected cases of hepatic metastasis. This approach presents low morbidity and good cosmetic result. The lack of alternative treatments and the poor prognosis of untreated cases have justified surgical resection in order to increase overall survival. Nevertheless, this approach should be performed by hepatic surgery expertise teams trained on advanced laparoscopic procedures.
A hepatectomia tem sido o tratamento padrão para metástase de origem não colorretal (NCR) metacrônica, principalmente quando o intervalo livre de doença é maior do que dois anos. A hepatectomia por laparoscopia tem se tornado padrão principalmente para as ressecções à esquerda, haja vista a menor morbidade, menor tempo de internação, reabilitação precoce e melhor resultado estético. Os autores relatam um caso de paciente com duas metástases metacrônicas (10 anos de sobrevida livre de doença), de etiologia não colorretal (adenocarcinoma de intestino delgado), tratada com segmentectomia lateral esquerda (lobectomia hepática esquerda) laparoscópica. Paciente apresentou boa evolução pós-operatória sem recidiva (seis meses de seguimento). Segmentectomia lateral esquerda laparoscópica pode ser satisfatoriamente realizada em casos selecionados de metástases hepáticas, acarretando menor morbidade e melhor resultado estético. A falta de tratamentos alternativos e o prognóstico reservado nos casos de metástases NCR não operadas justificam a ressecção com o objetivo de prolongar a sobrevida. No entanto, essa abordagem deve ser realizada por equipe especializada em cirurgia hepática com treinamento em procedimentos laparoscópicos avançados
